Aluminum cylinder heads

I went through the same process before deciding on the Promaxx heads. I wanted a good set of pre-assembled. I was seriously considering the Trickflow heads but they were out of stock everywhere.

As to the rest, Eddy, Speedmaster/Procomp the actual build quality seemed like a crapshoot. Some really liked em and had no issues just slapping them on... others thought they were anchor iron and/or needed a lot of work to make right. Saving a few bucks out of the gate only to pay a good machinist on the backside to makem right was very unappealing to me. IIRC the Promaxx slugs come from overseas.. all the machining and hand assembly is done stateside. I purchased from Promaxx directly. Decided to go with the smaller 63cc chamber a few days later. One email later I had an updated invoice in my inbox.. real nice people to talk to on the phone as well so they get extra points for good customer service.

GL!
